Description

The AA116-72LF is a 1-bit GaAs FET digital attenuator in a low-

cost SOT-5 package. The device has a Least Significant Bit (LSB)

of 15 dB and is particularly suited where high attenuation

accuracy, low insertion loss, and low intermodulation products

are required.

A functional block diagram is shown in Figure 1. The pin

configuration and package are shown in Figure 2. Signal pin

assignments and functional pin descriptions are provided in

Table 1.

Note 1: Exposure to maximum rating conditions for extended periods may reduce device reliability. There is no damage to device with only one parameter set at the limit and all other

parameters set at or below their nominal value. Exceeding any of the limits listed here may result in permanent damage to the device.

CAUTION: Although this device is designed to be as robust as possible, electrostatic discharge (ESD) can damage this device. This device

must be protected at all times from ESD. Static charges may easily produce potentials of several kilovolts on the human body

or equipment, which can discharge without detection. Industry-standard ESD precautions should be used at all times.

Electrical and Mechanical Specifications

The absolute maximum ratings of the AA116-72LF are provided in

Table 2. Electrical specifications are provided in Table 3.

Typical performance characteristics of the AA116-72LF are

illustrated in Figures 3 through 6.

The state of the AA116-72LF is determined by the logic provided

in Table 4.

Package and Handling Information

Instructions on the shipping container label regarding exposure to

moisture after the container seal is broken must be followed.

Otherwise, problems related to moisture absorption may occur

when the part is subjected to high temperature during solder

assembly.

The AA116-72LF is rated to Moisture Sensitivity Level 1 (MSL1) at

260 C. It can be used for lead or lead-free soldering. For

additional information, refer to the Skyworks Application Note,

Solder Reflow Information, document number 200164.

Care must be taken when attaching this product, whether it is

done manually or in a production solder reflow environment.

Production quantities of this product are shipped in a standard

tape and reel format.
